It would be nice to know what programming language you are using...

That's tricky with Unicode.

Was the filename in Unicode? Or was it some Chinese codepage? That can
make a very big difference...

You can't. Sorry, I've got a scientific education, so I'm rather
negative about being able to work with *every* kind of file. It is
possible to get things working without a problem on *nearly* every file
your client's might use, though.

Probably.

Sorry, I don't know anything about C and unicode. If you're not too deep
into the development phase, you might want to take a look at Python.
It's cross-platform, has support for QT, and even better: you can run it
on all supported platforms without compilation. You can also embed
existing C++/C code into Python for easy porting! As an example of
Python's power: a big lot of Google is programmed in Python.
